Description

       condor_restartrestarts a set of HTCondor daemons on a set of machines. The daemons will be
       put into a consistent state, killed, and then invoked anew.

       If, for example, the condor_masterneeds to be restarted again with a fresh state, this  is
       the  command that should be used to do so. If the DAEMON_LISTvariable in the configuration
       file has been changed, this command is used to restart the condor_masterin  order  to  see
       this  change.  The  condor_reconfigurecommand  cannot  be  used  in  the  case  where  the
       DAEMON_LISTexpression changes.

       The command condor_restartwith no arguments or with the -daemon masteroption  will  safely
       shut  down  all  running  jobs and all submitted jobs from the machine(s) being restarted,
       then shut down  all  the  child  daemons  of  the  condor_master,  and  then  restart  the
       condor_master.  This,  in  turn,  will allow the condor_masterto start up other daemons as
       specified in the DAEMON_LISTconfiguration file entry.

       For  security  reasons  of  authentication  and  authorization,  this   command   requires
       ADMINISTRATOR level of access.

Options

       -help

          Display usage information

       -version

          Display version information

       -debug

          Causes  debugging  information  to  be  sent  to  stderr,  based  on  the  value of the
          configuration variable TOOL_DEBUG.

       -graceful

          Gracefully shutdown daemons (the default) before restarting them

       -fast

          Quickly shutdown daemons before restarting them

       -peaceful

          Wait indefinitely for jobs to finish before shutting down daemons, prior to  restarting
          them

       -pool centralmanagerhostname[:portnumber]

          Specify a pool by giving the central manager's host name and an optional port number

       -name hostname

          Send the command to a machine identified by hostname

       hostname

          Send the command to a machine identified by hostname

       -addr <a.b.c.d:port>

          Send the command to a machine's master located at "<a.b.c.d:port>"

       <a.b.c.d:port>

          Send the command to a machine located at "<a.b.c.d:port>"

       -constraint expression

          Apply this command only to machines matching the given ClassAd expression

       -all

          Send the command to all machines in the pool

       -daemon daemonname

          Send  the  command to the named daemon. Without this option, the command is sent to the
          condor_masterdaemon.

Exit Status

       condor_restartwill exit with a status value of 0 (zero) upon success,  and  it  will  exit
       with the value 1 (one) upon failure.

Examples

       To restart the condor_masterand all its children on the local host:

       % condor_restart

       To restart only the condor_startdon a named machine:

       % condor_restart  -name bluejay -daemon startd

       To  restart  a  machine  within a pool other than the local pool, use the -pooloption. The
       argument is the name of the central manager for the pool. Note that one or  more  machines
       within  the  pool  must be specified as the targets for the command. This command restarts
       the single machine named cae17within the pool of machines that  has  condor.cae.wisc.eduas
       its central manager:

       % condor_restart  -pool condor.cae.wisc.edu -name cae17
